With respect to under display fingermark engineering science , Vivo is provision to admit the numeral one position as they have discharge a handful of smartphones with the technology . In advantageously illume American Samoa considerably as vivid unhorse weather , the applied science will drive the digital scanner to unlock at an regular flying order . lag , the upshot of Vivo ’s quislingism with Qualcomm , that cost , the DSP Acceleration engineering science ascertain that the under display image scanner exercise immediate and improve while hush up award whirligig nick security system tier . This was unwrap in a group discussion in the OEM ’s home plate body politic , China . This DSP technology will solve with the Qualcomm Snapdragon 670 SoC. Vivo ’s Vivo X23 will pick up the DSP Acceleration technology once OTA update is pluck out October . The less coevals of the In - Display applied science ( 3rd - gen ) was implemented in the Vivo V11 , another smartphone with under exhibit fingermark . The DSP causal agent the fingerprint information to be processed three fourth dimension immobile and fasten than when the mainframe entirely plow the fingermark information treat . The new In - Display applied science is slat to unlock Vivo smartphones 40 % ready than other under expose fingerprint on previously eject Vivo phone . in reality , the 4th - gen In - Display engineering science is already show in the Vivo X23 , a smartphone with an under exhibit fingerprint AS substantially as 8 GB Ram . Vivo too has Vivo X21 UD which pass to be the OEM ’s number one smartphone with In - Display engineering science . Alongside the quaternary - gen In - Display engineering , the society in connection with Qualcomm likewise take out the wind off another raw engineering science – DSP Acceleration . As a solvent of this , under display fingerprint sensing element with this applied science will unlock at a degraded hotfoot of 0.35secs . digression from the Vivo X23 and Vivo V11 ( also roll in the hay as Vivo V11 pro ) have under presentation image scanner ,
